Looking on line, this model is no longer available, with a price tag of over £100.
Unfortunately once the ink pad needs replacing, it’s a software fix to tell the printer it has been replaced – and then the pad needs replacing.
Sometimes you can find the software available for free on the web.
If you only apply the software fix, within a short while, printed documents will suffer from the transfer of ink from the ink pad (which is full).
This is why I won’t spend more than £40 on an Epson printer – because once the ink pad is full, it is uneconomic to continue to use the printer – and time to throw it away.
If you think Epson charges extortionate prices for its ink – wait till you find out how much a replacement ink pad is.
